Abstract (en)
The present invention relates to a power compartment and an engineering machinery with the same. The power compartment includes: a compartment; an engine, arranged in the compartment and having a cooling liquid flow path for cooling liquid to circulate; a radiator, arranged in the compartment and communicating with the cooling liquid flow path of the engine; a ventilation port, arranged on the compartment and used to introduce air for exchanging heat with the radiator or discharge the air which has exchanged heat with the radiator; and a noise-reducing unit, arranged on the ventilation port and including a first grille, a second grille and a first elastic part, wherein the first grille and the second grille are stacked along a thickness direction of a wall of the compartment, a distance between the second grille and the first grille is adjustable, the first elastic part pushes the first grille towards the second grille, the first grille includes a plurality of first air ports arranged in parallel and a first solid part located between the two adjacent first air ports, the second grille includes a plurality of second air ports arranged in parallel and a second solid part located between the two adjacent second air ports, and a projection of each second air opening in a plane vertical to a thickness direction partially or all overlaps a projection of the first solid part in the plane, so that air out of each second air opening drives the first grille away from the second grille.
